StopTech ST-65 | 6 piston Caliper

StopTech ST-45 | 4 piston Caliper - discontinued

ST-45 Calipers are used on the rear of the 4 piston 355mm Nissan 350z, 370z, Infiniti G35/G37, and nearly all 380mm 4 piston big brake kits manufactured prior to 2011. NOTE: The pad shape for the ST-45 has a very slight difference from the standard ST-40 caliper. Use of ST-40 shaped pads in a ST-45 caliper will result in improper pad wear and noise.
